Skies could clear up after two more days of rain, say meteorologists

The south-west monsoon aided by the low pressure in the Bay of Bengal and the strong monsoon winds of the Arabian Sea has been bringing heavy rains across Telangana in the last few days and it is likely to continue so for the next couple of days.

But, after that, there could be a spell of dry weather for two weeks interspersed with light to moderate rainfall in the region, including the twin cities, till about August 11, according to the meteorologists at the Telangana Development Planning and Development Society (TGDPS) here on Friday.

Senior weather consultant Y.V. Rama Rao informed that the clouds could clear up by day after tomorrow as the low pressure is likely move northward towards Odisha/West Bengal and later westward towards Bihar and Jharkhand westwards. This will shift the more rainfall activity to the north.

“After this episode of heavy rains, the monsoon is likely to become weak for at least a fortnight. The westerly winds from the Arabian Sea too will become weak and there appears to be no fresh activity forming in the Bay of Bengal, ushering in a dry period. However, there could be light/moderate rainfall,” he explained.

However, what the current spell of heavy rains has done is to almost bridge the rainfall deficiency in the State. What was -20% deficiency in June has become 9% excess in July. If 10.4 cm of rain only was received in June as against the normal of 13 cm, this month till date about 20 cm of rain was recorded against the normal of 18.4 cm. It has brought the overall rainfall deficit till date to just 3%, said Mr. Rama Rao.

The State’s cumulative rainfall from June 1 to July 25 is 30.5 cm as against the normal of 31.5 cm, with a deviation of -3%.

Within the Greater Hyderabad Municipal Corporation (GHMC) limits, cumulative rainfall during the period has been 22.4 cm as against the normal of 24.6 cm, with a deviation of -9%. Last year, during the same period, 40.7 cm of rainfall was received, so the difference this year so far has been -25%.

Districts of Nizamabad, Jagtial, Jangaon, Peddapalli, Nirmal and Mancherial continue to be deficient in rainfall this season.

The senior meteorologist noted that there has been an increase in extreme rainfall incidents recorded within the capital and in rest of the State where five to six days of peak rains within a week are occurring after a prolonged dry period, helping bridge the overall rainfall deficiency.

The heavy rains with thick cloud cover had an impact on the temperatures as well. The maximum temperatures are down by three-four degrees below normal in the range of 28-32 degree C. Minimum temperatures too have been two to three degree below normal in the range of 18-24 degree C, he added.
